The detailed description of invention

Burnisher of the present invention comprises the core material of elasticity and absorption. The absorbability of core material allows it The effect of washing agent clean solution storage tank is arranged. The elasticity of core material allows in use by extruding Can force clean solution to flow out core material. Core material also is soft, thus instrument can with The surface configuration of the object that cleans is consistent. This flexibility and the elastic energy of core material make cleaning Close contact between the surface of the surface of instrument and the object that will clean is in order to obtain good clear Clean performance.

The preferred absorption elastomeric material that can be used as the core material of this burnisher comprises various foams Shaped material. Foamed material can by many different comprise cellulose, polyester, polyurethanes, The material that other plastics and natural sponge are made. Preferred core material as this burnisher Foamed material comprises polyurethanes and cellulose.

This burnisher comprises the plastic mesh material of beginning to speak of basic encirclement core material.Plastic mesh material does not need to be bonded on the core material, though can carry out this bonding selectively.Preferably core material is close within the net materials that is fitted in encirclement, the core material of given shape remains in the interior position of net materials thereby make normally.Like this, make net materials to core material point pressure be arranged a little, so that help core material is remained in the position within the net outer cover, this is selectable, but preferred.On the contrary, the core material of slight pressurized applies very little outward pressure on net materials, and this helps to keep the complete open configuration (configuration of complete open net materials below will more fully describe) of net materials at it.

It is preferred that net materials applies little pressure to core material, thereby makes core material keep its flexibility and its ability as the storage tank of clean solution.Therefore, preferably within the net materials that surrounds, the compression degree of absorbent core material is not more than, do not compare when compressing with it, it retainable it the water absorbability at least about 60%, more preferably keep such absorbability at least about 80%, it also is most preferred keeping at least about 90%.Preferably the compression degree of core material its absorbability that is not less than that its keeps is the most about 100%, keeps the most about 95% also to be preferred, keeps the most about 90% also to be preferred.

The plastic mesh material of beginning to speak as everyone knows, can be as the outer cover material of this burnisher.Such material preferably passes through the serialgram or the pipe of the net materials on the basic plane of extrusion process technology manufacturing." basic plane " also do not mean that net materials must be flat sheet, as pointing out, because it is usually with tubular shape production; It means that net materials can be arranged and is orientated to flat sheet that this flat sheet has basic length and width and minimum thickness (promptly cut along the length of the pipe of producing, the side that cuts that stretches in the opposite direction flattens up to net materials)." begin to speak " to mean that net materials comprises many perforates of being surrounded by interconnected plastics strand.Strand and perforate be repeat patterns clocklike preferably." chamber " of the net materials of beginning to speak refers to the single opening of net, and it is surrounded by the plastics strand of adjacency.Preferably all there is essentially identical size and dimension in the chamber of given net materials, but different net materials can have the chamber of different size and shape.

Net materials is parallel to the length of the pipe of production, or the direction of the side of the sheet of producing, known be " machine direction " (MD).Net materials in the plane of net be perpendicular to the direction of machine direction is known " laterally " (TD).

The technology of making as the net materials of beginning to speak of the part of this instrument comprises the selection suitable resin material, and it can comprise that polyolefin, polyamide, polyester and other can produce the suitable material of durable and effective net.Low density polyethylene (LDPE) (LDPE, a kind of polyolefin), LLDPE (LLDPE), polyethylene ethyl acetate, high density polyethylene (HDPE) and their mixture, be preferably to be used for producing net materials described herein, although other resin materials also can replace, if its physical parameter of the net materials that obtains with here the definition consistent.LDPE is used for the most preferred resin of this net materials.

Except above-mentioned resin, additive material in the process of making the extruded net material, in resin, adding usually.Pigment, dyestuff, optical brightener, heavy wax and analog usually are the additives of making extruded net material described herein.

In order to produce the net materials of beginning to speak, the resin selected is fed among the extruder with any suitable device.In order to produce synthetic paper web and the extruder of beginning to speak to net and screw rod feeder equipment industrial be known with on sale.

Resin is incorporated into after the extruder, and it is melted, and enters into mould thereby flow through squeezing passage, as will be discussed in detail below.The temperature of resin fusing changes according to selected resin.The melting index of material is related squeeze film temperature and the canonical parameter (ASTM method D1238) that is extruded plastics viscosity when its flow through molds.Melting index is defined as the viscosity of thermoplastic polymer under specified temp and pressure; It is the function of molecular weight.Particularly, melting index is gram (gram) number of such polymer, at 190 ℃, and 3045 gram/square centimeter (g/cm ²) pressure can force the gram number of this polymer within following 10 minutes by 0.0825 inch (2.10mm) diameter orifice plate.

To LDPE and preferred its melting index from about 2 to about 14 of other resins of making net described herein; Melting index at least about 4 is preferred, also is preferred at least about 6; The most about 10 melting index is preferred, and the most about 8 also is preferred.If use is not LDPE but resin material, and melting index can suitably change.The temperature range of extruder operation can change between the temperature that the temperature and the resin generation of resin fusing are degraded substantially.

In order to produce diamond illustrated in figures 1 and 2 or the hexagon net materials of beginning to speak, can be with the resin extruded of liquefaction by two mutually despun moulds, this uses always industrial.The United States Patent (USP) 3 of livingston (Livingston) and plum forests (Melin), 957, No. 565 and Mel plug (Mercer) and Martin's (Martin) United States Patent (USP) 4,020, No. 208, described and utilized the opposite mould extruded tube that rotates to mould the technology of material net materials, such disclosure is hereby expressly incorporated by reference.The opposite mould that rotates has internal mold and external mold, and the both has separately along the vertical passage of cutting of their neighboring and inner rim, thereby when resin flow is crossed this passage, squeezes out fiber.Each fiber, F as shown in Figure 1 pushes out from each passage of internal mold and each passage of external mold, thereby forms wet end section 10.Because two moulds are with opposite mutually direction rotation, the passage of external mold aligns with the passage of internal mold with predetermined interval.Therefore the mixed with resin of liquefaction when two passages alignment, and the fiber (F as shown in Figure 1) that two extruding are come out is bonded together, till the squeezing passage owing to continuous rotation external mold and internal mold does not line up again.Because internal mold and external mold be mutually with opposite direction rotation, the passage of each mould repeats the continuous process of aliging and not lining up.The point that is bonded together at passage alignment and two fibers is commonly referred to as node (as the N of Fig. 1).

" mould diameter " measured is the internal diameter of external mold or the external diameter of internal mold.These two diameters must equate substantially so that the resin of avoiding spreading leaks between two moulds.The final diameter of the pipe of the net that the mould diameter influence is produced is though the diameter of mould is just controlled a parameter of webmaster final diameter.Although believe that the excursion of mould diameter is extremely wide, preferably about 2cm (centimetre) to being suitable for making various net described herein between about 15cm, mould diameter is preferred at least about 3cm, belongs to preferred at least about 6cm; With the most about preferred 10cm, the most about 8cm also is preferred, and the most about 5cm also is preferred.

Squeezing passage can change in the known various geometrical configurations of prior art equally.Square, rectangle, D shape, crescent, semicircle, keyhole and triangular duct are all known shapes of prior art, can be fit to produce net described herein.Rectangular channel is preferred concerning this net materials, though other passages also provide acceptable result.

Webmaster from the mould of opposite rotation, push come out after, it can have the feature in diamond chamber, when from machine direction with when laterally seeing (Fig. 1), each angle of four jiaos of diamond is each node N, four limits of diamond are four line segment F that form respectively.Then webmaster is pulled through columnar mandrel, the longitudinal axis of mandrel is basically parallel to the longitudinal axis of phase reversal moving mold, i.e. machine direction (as the MD that represents among Fig. 1).The effect of mandrel is that circumferential edge pressure is applied on the paper web (or fabric), thereby opens it a little on TD; This guarantees that also an infall has excellent contact, forms node securely at these points.General mandrel is in the solution of the water, oil or other chilling that are immersed in drum, and typically temperature is about 25 ℃ or lower; This is used to cool off and solidify the net that squeezes out.

Mandrel can have various diameters, though will select it to have and the corresponding suitable diameter of extrusion die diameter.The diameter of mandrel is more preferably greater than the diameter of mould, so that reach desirable firm node form and the stretching of desirable silk thread on TD.But axle diameter also must be enough little, so that avoid the globality by excessive stretching infringement net.The ratio of axle diameter and mould diameter more preferably at least about 1.3, also is preferred at least about 1.4 preferably at least about 1.1, and maximum is preferably about 2, and maximum more preferably about 1.8, the most about 1.6 also is preferred.

The pipe of net materials is preferably in machine direction (MD) longitudinal stretching of net; This make in the silk thread and node in the polymer molecule alignment, make net materials have required intensity and soft character.Depend on various factors, comprise temperature that system polymer into the net, net be cooled to, be applied to online draw speed and amount of tension; The silk thread that perhaps stretches separately, perhaps Wang silk thread and node both are stretched.If have only silk thread to be stretched, net materials seem still with Fig. 1 represent identical like that.

Preferably Wang silk thread and node both are stretched.Depend on how to watch webmaster, the geometrical configuration in net chamber also can change significantly.Therefore, the description of geometry cavity does not also mean that restriction, but only for illustrative purposes.When the node of diamond vestibule is stretched, they can with little bead-like object (as the N of Fig. 1) become long thin silk thread shape node (as Fig. 2 and 2A 12).Thereby the chamber also becomes hexagon with diamond, and the node 12 that wherein is stretched forms hexagonal two limits and four single silk thread section F form remaining four limit of hexagon.

The speed of preferably taking net away is supplied with the tensile force of required vertical or machine direction like this faster than the speed that it is produced.The general reel of getting net that uses accumulates completed net product.Should be very clear, many machined parameters are arranged (as the diameter of resin feeding rate, mould and mandrel here, the temperature of the design of passage, the rotary speed of mould, chilling, the amount of stretching and speed and other similar parameters) can influence net parameter, as the number in shape, Unit Weight and the chamber in chamber.

Though concerning making the net materials that instrument of the present invention uses, the net materials of beginning to speak of producing the pipe configuration by the mould that uses opposite rotation is preferred as mentioned above, also knows other processing unit (plant).For example, No. 4,123,491, the United States Patent (USP) of Larsen (Larsen), its disclosed content is hereby expressly incorporated by reference, and the net sheet of beginning to speak that its expression is produced when the silk thread of producing is mutually perpendicular substantially, forms the chamber of basic rectangle when machine direction and transverse direction are seen.The net materials that obtains is preferably on MD and the TD both direction after producing and stretches, so that make the polymer molecule alignment in the twine line.

The method that also has another to make the net materials of beginning to speak of extruding is described in Jia Funi and Larsen (Gaffney﹠amp; In No. 3,917,889, the United States Patent (USP) Larsen), its disclosed content is hereby expressly incorporated by reference.This list of references has been described the production of tubular extrusion net, and wherein the silk thread that pushes out in machine direction is basically perpendicular to the plastics silk line or belt of the crosscut machine direction that forms periodically.Can control the material that pushes out from the crosscut machine direction, thereby make it form thin silk thread or thick band.As the fabrication schedule of above-mentioned net, the tubular reticulum of making according to this list of references is preferably in circumference (TD) and vertically (MD) both direction stretching after extruding.

An important parameter of the net materials of beginning to speak of this instrument of being used as is " basic weight ".Because net materials is the plane substantially, basic weight is to determine with the weight of per unit area net materials.But must the careful unit are that defines net materials.This is soft because of net materials, and they open or shrink in different all directions, so the weight of each unit are can have very big variation.For example, Fig. 1 or 2 diamond or hexagon net materials can elongate in machine direction, thereby make the angle in the chamber of pointing to machine direction trend towards zero, and in fact the chamber is crimped onto is not laterally having width.In fact, because MD stretches and is applied to usually on such net materials when they are produced, generally be added to they on TD, be such " flatten ' state (be MD (Fig. 1; 2 and 2A in 14) angle that refers to is about zero degree with upwarding), need on TD, apply a spot of power so that they are opened and " opening " chamber over there.

The begin to speak basic weight of net materials is to determine by the area of measuring net when it " opens " entirely.Complete open net materials is a net, and wherein net materials is open at machine and horizontal both direction.Thereby do not have a plastic cord in fact also to be stretched and become longer, they are all stretching.To the net materials of rectangular cavity shape is arranged, net materials is to open in machine direction and transverse direction, and the line side of diameter rectangle becomes straight and is parallel to these directions.To the net materials shown in Fig. 1 and 2, they must open suitable distance in machine direction and transverse direction, thereby make four plastic cords that in net materials shown in Figure 1, meet at each crosspoint become straight and form four an angle of 90 degrees, make three lines that in the net that Fig. 2 represents, meet at each crosspoint become straight and form three 120 degree angles.

Net materials as this instrument has basic weight at least about 3.4g/m ²(gram/square metre), preferably at least about 6g/m ², more preferably at least about 8g/m ², at least about 10g/m ²Also be preferred; And the most about 34g/m of basic weight ², the most about 20g/m preferably ², more preferably the most about 15g/m ², the most about 12g/m ²Also be preferred.

When the net materials of beginning to speak as this instrument opened as above-mentioned definition, there were two pairs or three pairs of parallel sides in each chamber of net." the chamber size " of net materials is the mean value of size between two couple in each chamber or the three pairs of parallel lines.

An additional preferred parameter to the net materials that is used for instrument of the present invention is, its maximum of these sizes between parallel chamber side is not more than about 3 times of these size minimum of a values, preferably the maximum of these sizes is not more than about 2 times of these size minimum of a values, and it also is preferred for about 1.5 times that the maximum of these sizes is not more than these size minimum of a values.It also is preferred that these size maximums are not more than 1.2 times of these size minimum of a values.

The hole dimension of the net materials of beginning to speak of this instrument of being used as is about 0.5mm (millimeter) at least, preferably at least about 1mm, more preferably at least about 2mm, at least about 3mm also is preferred, also is preferred at least about 4mm, and the most about 10mm, the most about 8mm preferably, more preferably the most about 7mm, the most about 6mm also are preferred, and the most about 5mm also is preferred.

Another parameter of net materials of beginning to speak is " number of share of stock " or " chamber number " (as definition here, they is identical).From getting number of share of stock or chamber number perpendicular to all directions of net strand.To netting the net materials (rectangular cavity net, or the TD in Fig. 2 net) that has when opening entirely perpendicular to MD or TD strand, numeral is taken from a line that strides across so vertical strand along a certain direction simply; Calculating obtains identical number (except the difference that rounds up and may cause) with strand or chamber that this line intersects.To the net materials (all strands in Fig. 1 net, or the F strand in Fig. 2 net) of strand out of plumb MD and TD, numeral is taken from along a line of vertical these strands, calculates the strand or the chamber that intersect with this line.To most of net materials,, be identical approximately along the number of share of stock of each direction as those of Fig. 1 and 2.Can net materials be described with the mean value of two (as the nets of Fig. 1) or three (as the net of Fig. 2) number of share of stocks (" average number of share of stock " or " average cavity number ").

Be used for the average number of share of stock of the net materials of beginning to speak of this instrument or average cavity number and be being at least about 0.8/cm (root/centimetre), preferably at least about 1.0/cm, preferred at least about 1.2/cm, also be preferred at least about 1.4/cm, still be preferred at least about 1.05/cm; The most about 20/cm, preferred the most about 8/cm, the most about preferred 5/cm, the most about 3/cm also are preferred, and the most about 2.2/cm still is preferred, and the most about 1.8/cm is also still preferred.

The good soap lather characteristic that this instrument reaches needs the good flexibility of strand of net materials.A kind of method that reaches good flexibility is to make the strand of material very thin, and it mainly is to be determined by the number of share of stock of basic weight and net.But, the flexible influence that also is subjected to the plastics self character.

As described herein and illustrated in fig. 3, to as those of Fig. 1 and 2,, determined the code test that can realize the net materials flexibility with the net materials that diamond or hexagon chamber are arranged of tubular net materials production.Here the flexible measuring value that definition obtains is an initial elongation.As schematically illustrating among Fig. 3, webmaster 20 is stretched out by test stand horizontal arm 22, begin to determine the program of initial elongation, this arm supports that by vertical holding components 24 holding components is connected on the test stand base 26 successively successively.

As mentioned above, when extrusion molding begins to speak to net from the mould of opposite rotation, be form formation net with webmaster.The webmaster 20 that is used to test should have 6.0 inches (15.2cm) long, as length 28 indications.Select six inches and 50.0 grammes per square metres, as the appropriate criteria of measuring.To very clearly see, also can select other standard conditions.But for the initial elongation value of relatively more different nets, best selected standard conditions are with described herein consistent.

As illustrated in fig. 3, hang standardized weight from weight holding components 30, holding components has weight support level arm 32 to pass webmaster 20 and is hung out by it.Holding components 30 and standardized weight add together combination general weight, and to equal 50 grams be crucial.Distance 34 explanations are " initial elongation ", and this is the distance that webmaster extends immediately after weight is hanging on the webmaster 20.The most handy linear scale 36 measuring distances 34.

Certainly, initial elongation depends on the diameter of mould and the diameter of mandrel.Can come more different net materials with mandrel with the mould of same diameter.For example, the net that is used to make instrument of the present invention is to make on the machine of mould diameter 7cm and axle diameter 10.5cm, and net materials preferably has the initial elongation value at least about 30cm, more preferably at least about 33cm, at least about 35cm also is preferred, also is preferred at least about 36cm; Best the most about 43cm, more preferably the most about 39cm, the most about 37cm also are preferred, the most about 36cm also is preferred.

By initial elongation can be eliminated the dependence of the initial elongation value of net materials to mould and axle diameter divided by axle diameter.This provides " initial elongation ratio ", and it is used for relatively with the not isotype net materials made from mandrel.The net materials that is used for this instrument preferably has initial elongation than at least about 2.8, and more preferably at least about 3.1, preferred also have at least about 3.3; And preferably the most about 4.1, preferred the most about 3.7, the most about 3.5 also is preferred.

By on net sample 20, hanging bigger standardization weight (as 250 grams, as representing among Fig. 3) and deducting distance 34, can measure the elastic characteristic of the net materials of beginning to speak from distance 35.Holding components adds that it is crucial that total combination weight of bigger standardization weight equals 250 grams.The result is proportional to the spring level of net and is called " elasticity ".To being used to make the net materials of this instrument, the net materials that the equipment that promptly using has mould diameter 7cm and axle diameter 10.5cm is made, elasticity is preferably at least about 34cm, and is preferred at least about 38cm, at least about 40cm also is preferred, also is preferred at least about 41cm; And best the most about 48cm, the most about preferred 44cm, the most about 42cm also are preferred, the most about 41cm also is preferred.

To the net materials made from different moulds and mandrel, determine " the elasticity ratio " of net by remove it with mandrel, can also make this measurement standardization.The best flexible ratio of net materials that is used for this instrument is at least about 3.2, and is preferred at least about 3.6, also is preferred at least about 3.8, and preferably the most about 4.6, and preferred the most about 4.2, the most about 4.0 also is preferred.

Be generally used for making the begin to speak technology of net materials of preferred diamond and hexagon, this net materials is used to make this instrument, and the net of production generally shrinks severe at transverse direction, and somewhat elongated in machine direction.Net materials although it is so can be easy to open by draw it lightly at transverse direction, but in a single day this power on the transverse direction unclamp, and the elasticity of its nature tends to make its to shrink.

Preferably, when being used for making this instrument, the plastic mesh material of beginning to speak of Fig. 1 and 2 approaches their full open configuration.By drawing them to reach their full open configuration at TD lightly up to them, under the temperature that the improves fusion temperature of plastics (but be lower than), they are kept that state, do not need TD to try hard to keep to be held in full open configuration, to be loose at their full open configuration up to net materials is loose thereby can make such net materials.To preferred LDPE net materials, for example, just can accomplish this point about 15 minutes of the about 60 ℃ full open configurations that hold them in them.Similarly, as other net materials of this instrument, by they are kept full open configuration in certain temperature and time scope, also can or approach under their full open configurations loosely, this temperature and time is easy to be determined by experiment to every kind of material.

To burnisher of the present invention, core material topped by three layers or more multi-layered plastic mesh material at least about 50% surface.As used herein, " surface " of core material refers to its outer surface.Preferably core material is topped by three layers or more multi-layered net materials at least about 70% surface; More preferably core material is had an appointment 90% surface at least like this by topped.Most preferably all basically surface of core material is all topped (though the net materials that surrounds generally has several seams by three layers or more multi-layered net materials, each layer net materials is bonding or be melted in together there, thereby each layer can not be separated at such seam crossing).

In the situation of the core material that topped instrument of multilayer net materials arranged, the number of plies of the such net materials in set point place can have very big variation arbitrarily on the surface of instrument, and this depends on how instrument is manufactured.The average number of plies on the core material surface of the topped instrument of net materials preferably is 3 layers at least, and preferred is 4 layers at least, also be preferred be 6 layers at least, still preferred is 8 layers at least, it also is preferred being 10 layers at least, it also is preferred being 12 layers at least.The best maximum of the average number of plies on the core material surface of the topped instrument of net materials is 40 layers, and preferred maximum is 32 layers, also is that preferred maximum is 25 layers, and still preferred maximum is 20 layers, also is that preferred maximum is 16 layers, and preferred maximum is 12 layers.

In order to make this instrument can produce good and long soap lather perdurabgility when using with the washing agent clean solution, on the essential part of the surface area of instrument, many skins of net materials must be easy to move by each layer below it.The advantage that the fine foaming that is provided by this instrument is provided needs net materials each relative to them below of many layers layer can move, and mobile distance equals the chamber size of netting at least.The method of this instrument of making can promote to net the such relative motion of each layer.

The size and dimension of this burnisher is not crucial to forming above-mentioned good foaming feature.Because this burnisher is mainly used in manual clean surface, particularly tableware and cooking appliance, the size and dimension that makes things convenient for that hand uses is arranged so wish instrument.To this instrument many different geometric solid shapes can be arranged.

Also wish to be easy to make this instrument with commercial foam on sale and plastic mesh material.Almost can obtain foamed material with size and dimension arbitrarily.As the diameter of setting and the webmaster of indefinite length is that most convenient obtains plastic mesh material.

Preferred this burnisher is to make with the foam core material of the solid of shape approximation rectangle.The such core material plastic mesh material of handy multilayer is surrounded, common like this angle and the edge that obtains circle, thus making the burnisher of making is the pillow shape, as representing in the Figure 4 and 5.

Burnisher of the present invention preferably be about 5cm (centimetre) to about 20cm, wide about 4cm is to 15cm, thick about 2cm is to 10cm.The instrument of pillow shape is more preferably long at least about 7cm like this; Long also is preferred at least about 9cm; More preferably grow the most about 15cm, the most about long 11cm also is preferred.Such instrument is more preferably wide at least about 6cm, and wide also is preferred at least about 7cm; The most about more preferably wide 10cm, the most about wide 9cm also is preferred.Such instrument is preferred thick in 3cm, and thick also is preferred at least about 4cm; And preferred the most about thick 7cm, the most about thick 6cm also is preferred.

The laminated plastics net materials that surrounds absorbent core material can have the many different configurations and the method for the such net materials of lay.No matter plastic mesh material is how to center on the core material lay, preferably each layer of net materials links together by certain interval, thereby the layer of each layer relative proximity can not moved freely fully.Although need certain connection between each layer, the essential part of the instrument preferably net materials of each layer does not connect together mutually, so that reach relatively moving between each required layer of the good soap bubble effect of above-mentioned generation.In order to obtain this effect, the most handy point or line is bonding that each layer of net materials linked together.Preferably so bonding about 2cm that leaves at least, preferredly leave about 4cm at least, at least it also is preferred leaving about 5.5cm, at least it still is preferred leaving about 7cm, and their best maximums are left about 20cm, preferred maximum is left about 15cm, and it also is preferred that maximum is left about 11cm, and it still is preferred that maximum is left about 9cm.

The preferred configuration of this instrument is to have the level and smooth substantially net materials of many layers to surround core material, resembles very much on a pillow and is with many pillowcases.Such instrument explanation is in Fig. 4,4A and 4B.Fig. 4 is the perspective view of pillow shape instrument 50, and it has top 53, the end 54, side 51 and 52, end 55 and 56, and whole dimension is long L, wide W and thick D.Fig. 4 A is the profile along the instrument 50 of 4A-4A line intercepting, in the plane perpendicular to length L.Fig. 4 B is the profile of the instrument 50 got along 4B-4B line among Fig. 4, in the plane perpendicular to width W.

bonding seams

45,46,47 and 48 bond together all 4 layers of net materials.Seam 45 be whole length along side 51 from the end 55 to the end 56 the top 53 and the centres at the end 54 about instrument 50; Similarly, seam 46 is a whole length at side 52, seam 47 be along the end 55 whole width from side 51 to side 52, roughly in the top 53 and the centre at the end 54 of instrument 50; Similarly, seam 48 is whole width of 56 in the end.

Instrument 50 can be made with foam core material 40, and core material is the solid of rectangle basically, and its undersized is in the size of finished product instrument 50.The net materials that is used for tools 50 is preferably taken from tubular aforesaid existing net materials, and net materials preferably has the circumferential edge of pipe, when net materials opens entirely, is approximately equal to 2W+2D (though also can use than the great circle periphery pipe).Make tubular net materials form concentric tubular layer then, they are roughly level and smooth, and every layer length preferably slightly is longer than L.This can do like this, cuts the tubular net materials that a plurality of length slightly are longer than L, with they one be placed on another the inside, equal the required number of plies of net materials (is four layers to instrument 50) up to a number of concentric tube in another the inside.Another kind is, can carry out the concentric tube of this lay net materials like this, length slightly is longer than the length of the tube of web material of L, make outside its internal turn, it is gone back on the remainder of pipe, repeat this action up to forming the required number of plies (is 4 to instrument 50).

(as turnstile or mandrel) is easy to form the net of multilayer on the object that can expand, thereby the concentric tube of net is remained on this object net is opened entirely.Though net be remain on it like this open configuration entirely, preferably its is placed one required period improving under the temperature so that can make net materials loose, thereby when it still keeps its full open configuration when Extended Object is removed.Another kind is before its lay is become concentric tube net materials is opened entirely with loose.

Preferably side seams 45 and 46 bonding all stratum reticulares, and they are concentric tube at net bonding after loose (stitch 45 and 46 can so bonding before loose).Can each layer of net materials is bonded together or use adhesive that they are bonded together by heat seal, form each bar seam.Using ultrasound ripple or other known methods can obtain heat seal.

If the circumferential edge of the concentric layer of tubular net materials is approximately equal to 2W+2D, in case finish side seams 45 and 46, the webmaster of lay just can carry out the processing of second step.If this circumferential edge is greater than 2W+2D, the concentric webmaster that can make required circumferential edge length with seam 45 and 46, as long as seal along the suitable line that is parallel to webmaster length simply, then excision surpass these sutures any excess stock just.For fear of the waste net materials, the circumferential edge of the preferred net tubes of material of selection should be approximately the integral multiple of wanting the required Zhou Bianchang of tools (2W+2D).If the circumferential edge of net is two times or many times of 2W+2D, can do the net materials concentric tube of two or more instruments, side by side make one or more wide sealing seams by being parallel to webmaster length, then (or another kind of method is in the middle incision of stitching like this, the sealing seam of making two pipes is right after together, cuts in the middle of them then).

Above-mentioned operation obtains the concentric layer of one or more tubular net materials, and its circumference length of side is approximately equal to 2W+2D when net opens entirely, and its length slightly is longer than L.If side seams 45 and/or 46 outstanding or more coarse than inboard in the outside of net multilayer pipe preferably is inverted to the outside to the inboard, thereby a more level and smooth side that makes seam is in the outside.This is because usually catch instrument 50 along side 51 and 52 in use, catches the pleasant cause of level and smooth seam.

Now rectangular solid core material 40 is inserted in the multilayer webmaster, end is entered earlier, is all surrounded by webmaster up to it.The side seams 45 of webmaster and 46 is preferably alignd with the side 51 and 52 of core 40.Because the length of multilayer webmaster is slightly larger than the length of core 40, core 40 can be positioned at wherein like this, and within webmaster, 55 and 56 can make

end seam

47 and 48 along the end, thereby core 40 is enclosed in the net materials fully fully for it, and instrument 50

completes.End seam

47 and 48 can be similar to side seams 45 and 46 with heat seal or adhesive seal.Any net materials that surpasses

end seam

47 and 48 preferably excises.

Be easy to recognize, can manufacture the multilayer webmaster and make its length, thereby can make two or more instruments with a multilayer webmaster significantly greater than the length L of individual tool.
